Troubleshooting an Aggregated Ethernet Interface
The show interfaces terse command shows that the LAG is down.
Check the following:
- Verify that there is no configuration mismatch.
- Verify that all member ports are up.
- Verify that a LAG is part of family ethernet—switching (Layer 2 LAG) or family inet (Layer 3 LAG).
- Verify that the LAG member is connected to the correct LAG at the other end.
- Verify that the LAG members belong to the same switch (or the same virtual chassis).
